利用步进电机构成雷达方位角录取系统的探讨

Radar Bearing Extraction System by Stepping Motor

本文提出了一种利用步进电机构成雷达方位角录取系统。因为步进电机能够将电脉冲转换 成相应的角位移,所以只要通过对电脉冲频率进行控制,就可以实现对天线转速的控制,而且通过对脉冲 个数的计数就可以确定天线所转的角度,实现方位角的录取。该系统与其它的方位角录取系统相比,具 有结构简单、工作可靠、系统调试方便等优点,其精度完全满足船舶导航雷达的要求。

In this paper, a radar bearing extraction system aided by a stepping motor is presented. Because the stepping motor is able to convert pulses into appropriate angle displacements, the rotating angle of the attenna can be determined and the extraction of the bearings realised through counting the number of pulses. Compared with any other methods, the one proposed here is simple, accurate and reliable.
